Playing with Parity

In the Playing with Parity Circle, students learn about parity through playing games and learning magic tricks. The Circle is an opportunity for students to play with and explore parity – to deepen their understanding of what it means for a number to be even or to be odd, and to draw connections between the games and the games’ various uses of parity as a mathematical tool and concept.
